6. In games of cooperation, explain how the repetition of
play may affect the possibilities of cooperation compared with one-shot games. Illustrate your answer with an example.
7. Explain the purpose and the mechanism of signaling in games with incomplete information. Illustrate your answer with an example.

Слайд 13Section A
1 conceptual question:
e.g. explain the meaning of mixed strategies
in evolutionary game theory...
e.g. explain what the guessing game tells us about players’ rationality...
1 definition question: 3 definitions.
e.g: A Nash equilibrium in mixed strategies, Subgame perfect equilibrium, The Winner’s curse.

Find the NE (sequential, simultaneous games,
repeated etc.)
Bargaining games, cooperation games etc.
Find the NE is games of Cournot and Stackelberg.
Find the ESS. Are the NE evolutionary stable?
